LLC Partnership Tax Software: What You Actually Need for Form 1065 and K-1s

If you run a multi-member LLC and are shopping for tax software, the short answer is this: you need a tool that can file Form 1065 and generate a Schedule K-1 for every member — and most tax-only programs do exactly that, as long as your books are already accurate going in. TurboTax Business, TaxAct's partnership product, and ProConnect Tax Online will all produce a filed return. None of them track what actually happened to each partner's capital account during the year, which is the information Form 1065 and the K-1s depend on in the first place. That gap — not a missing feature in the tax software — is where most partnership returns run into trouble, and it's what the rest of this comparison focuses on.

What makes partnership/multi-member LLC taxes different

A single-member LLC usually reports on Schedule C and attaches it to the owner's personal return. A multi-member LLC is, by default, taxed as a partnership, which means it files its own information return and splits the tax consequences across every member. That changes what the software — and whoever is doing the bookkeeping — actually needs to track.

Form 1065 basics

Form 1065, U.S. Return of Partnership Income, is an information return — the partnership itself doesn't pay income tax. Instead, it reports total income, deductions, gains and losses, then passes each member's share through via Schedule K-1 (IRS, About Form 1065). For a calendar-year partnership, the original due date is March 15 (the next business day if the 15th falls on a weekend), with a six-month extension to September 15 available using Form 7004.

Schedule K-1 for each member

Every member gets their own Schedule K-1 showing their share of income, deductions and credits for the year. The partnership generates all of them from the same return, and the figures have to tie back to what each partner actually contributed and withdrew — not just an even split of profit. Members then use their K-1 to file Form 1040, so an error on the partnership return shows up on several personal returns at once.

Partner capital accounts

Since the 2020 tax year, the IRS has required partnerships to report partner capital accounts using the tax basis method — tracking actual contributions, each partner's share of income or loss, and distributions, rather than GAAP or other methods partnerships could previously use. In practice, someone has to log every contribution and distribution as it happens, per partner, in dollars. Software that only opens in February can't reliably reconstruct twelve months of that activity from bank statements alone.

Partnership tax software compared

Based on currently published pricing, here's how the main options line up for a multi-member LLC filing Form 1065:

TurboTax Business

What's priced at $639 federal (plus $69 per state) is specifically TurboTax Expert Assist Business — the tier that includes unlimited help from a live tax expert as you go, not a bare-bones do-it-yourself version. Intuit also sells a Full Service tier, where an expert prepares the return for you, starting around $1,549 for partnerships, with add-ons like an extra Schedule K-1 priced separately (TurboTax, Business tax filing). If you're comparing prices specifically to find the cheapest self-service option, confirm which tier you're looking at — the online product pages lead with the expert-assisted pricing first.

TaxAct Partnership/LLC

TaxAct sells its partnership and LLC product as downloadable software starting around $159.99 for the federal return, with state editions priced and sold separately. It's generally the cheapest of the three for a straightforward do-it-yourself return and handles the same core job — Form 1065 and K-1 generation — with a more bare-bones interface than TurboTax. Like TurboTax, it assumes you're arriving with finished books, not building them as you go.

ProConnect Tax Online

ProConnect is Intuit's professional-grade product, used by accountants and tax preparers rather than individual business owners. Current published pricing runs from $2,478/year on the Essentials 50 plan up to $8,462/year on the Advanced plan, with tiers in between and an additional per-user access fee on top (Intuit ProConnect, pricing page). For a single multi-member LLC, that's priced well beyond what makes sense — ProConnect is built for a practice filing many returns, not one partnership filing its own.

All-in-one accounting + tax platforms

This category — where Kangaroo ERP sits — treats bookkeeping as the foundation instead of a separate step that happens before tax software opens. The pitch isn't that it replaces the tax form itself; it's that the numbers feeding into Form 1065 — contributions, distributions, income and expenses — are recorded and reconciled continuously, so whoever ultimately files the return (you, your accountant, or a tool like TurboTax or TaxAct) is working from clean records instead of a year of loose bank statements.

Why tax-only software isn't enough for multi-member LLCs

Every tool in the first three rows of that table does the same basic thing: it takes finished numbers and turns them into a filed return. That's useful, but it assumes the hard part is already done. For a multi-member LLC, the hard part usually isn't filling out Form 1065 — it's knowing exactly what each partner put in and took out over twelve months.

Tracking partner contributions and distributions year-round

In a two- or three-member LLC, it's common for partners to contribute unevenly — one puts in cash at formation, another contributes equipment, a third makes a mid-year capital call. Distributions are just as uneven: one partner draws monthly, another waits until year-end. If none of this is logged as it happens, reconstructing it in February from bank statements and memory is where K-1 numbers start to drift from reality, and where members end up disputing their own K-1.

Reconciling books before K-1 season

Tax software can't fix a bank account that was never reconciled. If expenses were miscategorized, a partner loan was logged as a distribution, or personal and business spending blurred together during the year, TurboTax Business or TaxAct will still produce a return — it just won't be an accurate one. Reconciliation has to happen in the books first. Waiting until the tax-only software is open to discover the gap is one of the most common reasons partnership returns get filed late or amended.

How Kangaroo ERP handles partnership LLCs end to end

Kangaroo ERP is a bookkeeping and tax-prep platform, not a Form 1065 filing tool — it's worth being precise about that distinction, because the two are easy to conflate. What it does for a multi-member LLC is keep the underlying records clean throughout the year so that whoever prepares the 1065 and the K-1s — your accountant, a CPA, or a tax program like the ones above — is starting from accurate numbers instead of a mess of transactions to sort out in March. In practice:

• Income and expenses are categorized continuously, not reconstructed at year-end from bank statements.
• Contributions and distributions can be logged per member as they occur, instead of estimated after the fact.
• Bank reconciliation happens on an ongoing basis, so the books are already in order by the time your accountant sits down to prepare the 1065.

We're not positioning Kangaroo ERP as a replacement for your accountant or for Form 1065 software itself — for the actual filing and K-1 issuance, you'll still work with a tax preparer or a dedicated partnership tax product. What Kangaroo ERP removes is the February scramble of figuring out what each partner's capital account actually looked like all year. If you're weighing bookkeeping-plus-tax approaches against a tax-only tool, our comparison of LLC tax software vs. a CPA and our 2026 LLC tax deadline guide cover the filing side in more detail. You can see how the tax module works directly on the Kangaroo ERP taxes page.
